The two-minute version

Astronomers report that interstellar comet 3I/ATLAS contains an unusually large amount of methanol, a chemical fingerprint distinct from comets that formed in our Solar System.

Why it matters

The methanol anomaly is a separate finding from the age estimate and bears on how 3I/ATLAS formed. Watch for the underlying spectroscopy data to be published.
